Tap to retry the download and as it's attempting to download it again hit the pause button (you have to be quick!). Once paused, hit the button again to resume the download and see if it successfully completes.
thanks for the tip. I tried my best. that pause button is there a split second. I tried holding my finger, tapping fast, timing, whatever, can't seem to get the pause button to activate. I mean, it is there a literal split second.
